Patent JP-H0622470-A (JP)
Title: Semiconductor charge controller
Inventor: SUGAYA ATSUSHI
IPC: H02J7/24
Filed: 1992-07-07
Abstract: PURPOSE:To provide a semiconductor charge controller adapted to be integrated with a small circuit scale to prevent a switching loss and an increase in an electromagnetic induction noise by temporarily enhancing a switching frequency due to switching noise and disturbance if a field current of a generator for a vehicle is PWM-controlled by a semiconductor power switching element. CONSTITUTION:The semiconductor charge controller comprises a latching circuit 1 to be operated by a basic pulse 1a of a PWM from a PWM generator 2 to limit a pulse change of the PWM for driving a field current controlling semiconductor power switch 52. Thus, an increase of the switching frequency to a PWM frequency or more is suppressed, and a switching loss of the switch due to a high speed switching and electromagnetic induction noise can be reduced.

IPC: H01L21/30
Filed: 1980-12-24
Abstract: PURPOSE:To eliminate residual resist and improve the deficiency of fine pattern resolution, as well as enhance the quality of resist surface, by repeating an ON process to inject developer and to rotate a substrate and an OFF process where neither injection nor rotation is taken place. CONSTITUTION:The resist film coated on a substrate is exposed in accordance with a designated pattern. And then, the resist film is injected with developer, and the substrate is rotated to develop a designated pattern. At the same time, an ON process for injection of developer and rotation of the substrate, and an OFF process, where neither injection nor rotation is taken place, are repeated for a certain interval of time. This eliminates the residual resist and the deficiency of fine pattern resolution at the time of developer injection. This stabilizes the surface quality and reduces wasteful developer in use.
